This invention relates `methods'ofV andanparatus for the manufacture `of fabrics; such "as cloth or the like, which is formed ,ofV aseriesnf threads wherein oneset ,oijparallelthreadsis stitched together by a second and thirdseries of threads'. ,f

According to the present invention, a number of adjacent strands are intermittently led in a forward direction, and reciprocated .intermittently in a transverse direction, meansbeing-,provided whereby the strandsare stitchedtogether during the pause'iny the` combinedv intermittent movement.

In a mode of carrying out the invention, a. series of ,needles are'arranged in a movable frame rreciprocating so that the A.needlesrthereoniwill pass through the longitudinal strands, the thread from the needle being engaged byvthe-hookgof a rotating. shuttle, and carried around such shuttle so as to encircle the thread from the bobbinwithin the shuttle, and, as they needles return, the transverse movement of the strands* will cause the next locking stitch -to anadjacent strand, thus joiningthe strands together bylock stitches. f

The synchronization betweenthe 'shuttles and the needlesrwillbe obtainedV by suitable mechanical means, e..g. theneedle carrying framegmay be reciprocated by means-operatediroma train of gearing, which also rotates shaftsfor operating the shuttles. carried upon a movable table adapted to have an intermittent'- reciprocating lateralk Amovement. The strands on thisplate Vare suitably guided kthereon and the; needles in the needle carrying` frames are staggered and spaced apart so that on the downward'movement 'of the needle, aV

stitch is obtained through or V*between` -the strands'passing beneath each needle and, on the return of the needle the table moveslate`ra1ly andthe longitudinalstran'ds moveiorwardly so that the next downwardv movement of such needle will pass through an adjacent -thread,"or'the thread or threads next to such adjacent "thread, as desired. From'this position,`fas `soonfas Vthe needles return `clear of the strands, ajfurther lateralmovement of the tablev will take place,.

with the consequent forwardnnovernent of the strands, and a'further stitchfmade. The plateon its next movement, will return` in theV other direction and the needles will again pass through an adjacent strandfthus forminga zigzagstitch throughout the length of.v the material, 'each row of needlessirnilarly dealing with theintervening ApplicationSeptember 2, In New Zealand Serate-,inlieif` 19, 1.93.2v Y u Theflongitudinal strands are v mechanism.
